9C: The Mathematical World - Shapes
(grades 3-5, page 223)
Length can be thought of as unit lengths joined together, area as a collection
of unit squares, and volume as a set of unit cubes. (1 of 6)
Standard 10-1 page 51, Grades K-4
Understand the attributes of length, capacity, weight, area, volume,
time, temperature, and angle
Standard 12-5, page 112, Grades 5-8
Understand and apply geometric properties and relationships
If 0 and 1 are located on a line, any other number can be depicted as a
position on the line. (2 of 6)
Standard 9-4 page 48, Grades K-4
Relate geometric ideas to number and measurement ideas
Standard 5-5, page 87, Grades 5-8
Represent numerical relationships in one- and two-dimensional graphs
Graphical display of numbers may make it possible to spot patterns that
are not otherwise obvious, such as comparative size or trends. (3 of 6)
Standard 11-2 page 54, Grades K-4
Construct, read, and interpret displays of data
Many objects can be described in terms of simple plane figures and solids.
Shapes can be compared in terms of concepts such as parallel and perpendicular,
congruence, similarity, and symmetry. Symmetry can be found by reflection,
turns, or slides. (4 of 6)

Areas of irregular shapes can be found by dividing them into squares and
triangles. (5 of 6)
